Hi all,
Walkersea's and Cowski's replies are perfect. I'd just like to add a small "caveat":
when you use a measure parameter in a function which employs the internal parameter "t", the measure param will be used with its initial value regardless of the variation of "t" throughout the function.
For example, let's say you have a law curve depending on "t", which drives a feature where a measure param is placed; in its turn, this measure param is used in another law curve: well, in this case the second law curve won't follow the variation of the first, because the measure param it contains will remain "blocked" at the value it had when it was first evaluated...
Very strange thing of NX2, maybe this has been enhanced in NX3 and further...
Regards
